Smith Creek Previous Drill Program
- There were 5 drill holes total in the 2021 drill program. These were on roughly 1km spacing and followed the trend of the playa, with all being roughly 1km from the southeast contact with alluvium. The drill program showed the near surface waters too have some good indicators of lithium concentrations that need to be followed up. It also showed the lithium was not actively precipitating in the near-subsurface, so it probably stayed in suspension, at least for the first 100m of depth tested, indicating necessary follow-up work.
- The first hole targeted the northern zone, with the lowest resistivities seen near surface, showed lower (<7) pH values which indicates brines and lithium flows
- The next two holes uncovered a large northwest trending structure in the middle of the claim block and the fluids that potentially pool against/in it
- This zone shows higher pH values (8.1-9.2). It also has the lowest magnesium to sodium ratios of the holes with intercepted brine. This indicates the possibility of a large lithium brine system
- A major interpreted fault is shown on Figure right and follows a line of hot and cold springs. This fault dips steeply into the valley and taps ascending thermal waters seen on surface for over a mile of strike length. Lithium rich salts are being deposited from the hot springs
- It is believed the active hydrothermal system in the basin has kept water pH low enough in the brines for lithium to exist in solution. As such, the current claim block follows and interpreted NW/SE trending structure seen as a fluid barrier or conduit for brine
- Proposed exploration will test the most saline brines and define the brine size, flows and lithium contents
Hypothetical cross-section cuts the bounding fault which controls the location of thermal springs on the west side of the Smith Creek Valley Property. Percolating, meteoric water are believed to pick up lithium ions which percolate downward and is heated by hot water which enhances the solubility of lithium and increases the concentration within the brine.
